Imagine painting with watercolours, only way simpler. Introducing the Molotow Aqua Ink Pump Softliner! These pens are filled with water-based ink, and they are equipped with a soft brush tip. The ink can be used with water, but you can also just mix the colours however you like, right on the paper! They are refillable, and the nib can also be changed, if needed. The ink is only somewhat protected from UV rays, so we recommend that you either keep your paintings in a briefcase or treat them with a lacquer or fixative with strong UV-filters in them.
